The ingredient beneficial to human body such as phytochrome, vitamin, therefore a kind of tealeaves essential oil for concentrating mass efficient ingredient in tealeaves
It must be had broad prospects by the welcome of the majority of consumers.
Summary of the invention
The purpose of the present invention is to provide a kind of extracting method of tealeaves essential oil and obtained tealeaves essential oils, solve existing mention
The problem for taking the method recovery rate of effective component in tealeaves low.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of extracting method of tealeaves essential oil, including：
Freezing：Tealeaves is placed in -4 DEG C of environment below and is freezed；
It is broken：The tealeaves not yet to thaw is placed in crusher and is crushed, the tea powder freezed；
Water-removing：It finishes to the tea powder of frost, obtains tea thick slurry；
It extracts：Tea thick slurry is mixed to the extraction for carrying out effective component with solvent, is separated by solid-liquid separation, is obtained after the completion of extracting
Liquid phase rich in effective component；
Concentration：Liquid phase is concentrated, tealeaves essential oil is obtained.
Preferably, tealeaves is first impregnated 2-3h in a solvent before the freezing step.
Preferably, being crushed using wall-breaking machine to the tealeaves not yet to thaw in the destruction step.
Preferably, the water-removing uses microwave de-enzyming, fixation time 5-7min.
Preferably, being filtered to obtain filtrate and filter cake to the tea thick slurry, filter cake is mixed with solvent and is mentioned
It takes, filtrate is concentrated after merging with the liquid phase.
Preferably, the solvent is ethyl alcohol and/or water, the extraction process, solid concentration 15- in extracting solution
50%.
Preferably, temperature is 50-70 DEG C, pressure 0.005-0.01MPa in the concentration step.
Preferably, the separation of solid and liquid also obtains solid phase residue, it is secondary that the solid phase residue mixes progress with solvent
It extracts, secondary separation is carried out to extracting solution after the second extraction, and isolated liquid phase is concentrated.
Preferably, the solvent separated in the concentration step is for immersion and/or extraction step.
A kind of extracting method according to above-mentioned tealeaves essential oil obtains tealeaves essential oil, and wherein solvent content is less than 5%.
Compared with prior art, beneficial effects of the present invention are at least one of following：
The extracting method of the tealeaves essential oil of the application freezes tealeaves before extraction, due into the cell containing big
The moisture of amount, to destroy cell wall, is conducive to the dissolution of wherein effective component so cell can also expand in refrigerating process.
Before freezing, for guarantee tea cell in there are enough water energys enough to burst cell wall, cell membrane, first to tealeaves into
Row impregnates, it is made sufficiently to absorb water.
When tealeaves not yet thaws, tealeaves is crushed, because more crisp in its tissue of the tealeaves of freezing state,
It is more vulnerable to destroy in shattering process, receives the effective component in the cell of destruction and be easier to dissolve out.
Since microwave de-enzyming simultaneously can uniformly heat tealeaves inside and surface, heated uniform of tea powder can be improved
Degree, improves efficiency and effect.
